Abstract
The invention relates to laser materials and specifically to single crystal active media for solid state lasers operating in the middle-infrared (Mid-IR) 4-5 μm range of optical spectrum, wherein a cross section of stimulated emission and laser wavelength is shifted to the range of atmospheric transparency with a single crystal orthorhombic structure with space group D-Fddd. The material contains Lead, Gallium, Sulfur and is doped with Dysprosium according to general formula: PbDyGaS, where 0.0001<x<0.05. Lasers operating in this matter and in this spectral range are advantageous for lidar applications, free space communication, environmental monitoring, and other purposes.
